Hi all this is my first post but I've been lurking here about 2 yrs.GREAT FORUM! I got my hot blast (1557m) last year and it took me about 4 months to learn how to burn it.I have a fairly good draft(.[email protected]
F) and it goes down from there.Last year I had to leave the ash door cracked open to get this thing to reach 350 stack temp to heat my house.(stick on temp gauge)So this summer I drilled a second hole in the ash door(2' dia.)To adjust the draft I made a round peice of sheet metal with a screw and a spring for friction.Now I leave the factory air open all the way(most of the time) and adjust the air with the new adjuster.I know this may not be Kosher but It works well and doesn't ever run to hot.Although these hot blast furnaces are not ideal for anthracite coal then can work well.I am sitting here today and it's 17 outside and 74 in here.I'm about 50 miles N of Bimghampton NY. BTW last year before I bought my hot blast I prepaid for my fuel oil 3406.00.My coal bill for last year was 1789.00 and I used 138 gals of oil(in the spring and fall I use some oil when the draft is low).BOY AM I A HAPPY CAMPER.
THANKS ALL FOR YOUR ADVICE OVER THE PAST YEARS
